Synthesis and crystal structure of N1,N2-dimethylethanedihydrazide

Abstract

The title compound, N1,N2-dimethylethanedihydrazide, C4H10N4O2, was obtained by the methylation of oxalyl dihydrazide protected with phthalimide. The molecule is essentially non-planar with a dihedral angle between the two planar hydrazide fragments of 86.5 (2)°. This geometry contributes to the formation of a multi-contact three-dimensional supramolecular network via C—H...O, N—H...O and N—H...N hydrogen bonds.
